| 摘 要： | Poplar is one of the dominant tree species for the establishment of fast growing plantations in Shandong Province.Eighteen poplar clones belonging to Populus aigeiros section were introduced from Italy, Turkey and domestic regions. Populus deltoides cv. ‘Lux‘ 1-69/55 (1-69), which was widely used in Shandong Province, China, was taken as control clone (1-69).Following a randomized complete block design, seedling test and controlled afforestation trials were carried out at Juxian County,Caoxian County and Laiyang City. The results showed that the poplar clone (Populus x euramericana cv. ‘102/74‘), namely 102/74, performed well both in terms of adaptability and growth rate. The mean height of 13.9 m (H), diameter at breast height of 18.0 cm (DBH) and volume growth of 0.1445 m3 (V) were 2.2 %, 21.6% and 52.9% higher than those of 1-69 (CK), respectively,at the age of 5 years at three experimental sites. Moreover, the clone can be propagated easily and showed high resistance to poplar disease, pest as well as salinity and had longer growing period. Furthermore, wood basic density and fiber length of new poplar clone (102/74) were as same as 1-69 (CK). It was concluded that the selected clone (102/74) was ideal for the estab-lishment of fast-growing poplar plantations, especially for the pulpwood plantations in Shandong Province.

| Abstract: | Poplar is one of the dominant tree species for the establishment of fast growing plantations in Shandong Province. Eighteen
poplar clones belonging toPopulus aigeiros section were introduced from Italy. Turkey and domestic regions.Populus deltoides cv. ‘Lux’ I-69/55 (I-69), which was widely used in Shandong Province, China, was taken as control clone (I-69). Following a randomized
complete block design, seedling test and controlled afforestation trials were carried out at Juxian County, Caoxian County
and Laiyang City. The results showed that the poplar clone (Populus x euramericana cv. ‘102/74’) namely 102/74, performed well both in terms of adaptability and growth rate. The mean height of 13.9 m (H), diameter
at breast height of 18.0 cm (DBH) and volume growth of 0.1445 m3 (V) were 2.2%, 21.6% and 52.9% higher than those of I-69 (CK), respectively, at the age of 5 years at three experimental
sites. Moreover, the clone can be propagated easily and showed high resistance to poplar disease, pest as well as salinity
and had longer growing period. Furthermore, wood basic density and fiber length of new poplar clone (102/74) were as same
as I-69 (CK). It was concluded that the selected clone (102/74) was ideal for the establishment of fast-growing poplar plantations,
especially for the pulpwood plantations in Shandong Province.
